i bought this car charger from Anker ("press here") , but i don't know what is the suitable Usb cable the i have to buy , is there any specs for this or any tricks i have to know it before i purchase any cable ..??

regarding the Qi charger , i need a product that will not cause any heat or over charging of the battery , since i used to put the cell phone in the charger at night and sometimes i forget to pull it out from the charger , i saw some posts indicating there are some Qi charger will stop charging automatically when the battery become full , that is will be awesome soon as the nexus 5 battery is not removable one .
and also i heard that most of the Qi charrger need to place the nexus 5 centered or in aligned position with the charger otherwise it will not work.
